Downgrade protobuf

[NoPlagiarism]

protobuf>=3.19.5 => protobuf==3.20.3

What happened?

TypeError: Descriptors cannot not be created directly. on this line when using protobuf 4

Why

Major updates described there: https://developers.google.com/protocol-buffers/docs/news/2022-05-06#python-updates

Solution

I guess it's temporary solution without rewriting demoparser. Latest protobuf 3 and all

If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:
 1. Downgrade the protobuf package to 3.20.x or lower.
 2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).
